A method that utilizes extracts from fruit peels, stems, and leaves to formulate an odor control agent. It employs atomization equipment to spray the agent, which then undergoes a chemical reaction with odor molecules in the air to achieve the purpose of eliminating unpleasant smells. It is non-flammable and easily degradable; this technology has been applied in landfills, waste-to-energy power plants, garbage transfer stations, sewage treatment plants, paper mills, leather factories, chemical plants, food processing enterprises, livestock farming, and more.
